We're seeing a similar set of crashes as when this patch landed previously.  I'm rolling it out to see if that fixes the crashes again.  Here are some of the crash stacks:

I'd love to see some help on getting these resolved, rather than just reverting every time.

Yop. I already fixed the v8 problem, and had a r+ patch on the original bug report, 12437, was about to land it :(

Niko, is this rollout related to that? I thought this was separate (though still something I need help with).

Sorry, I mixed up the patches. Adam reverted the SVGImage patch, not the animVal patch.
The regressions due to the animVal patch should be fixed now, I landed the patch some minutes ago.

I don't think I'll be much help in resolving this issue.  I don't know much about SVG or painting.  Maybe emailing webkit-dev would turn up someone who can help?

I'll take a look at this in next week since my local SL can have repro.
